Reading the Landscape Before You Start a Moorland Hike

Start With the Shapes, Not the Route

Most hill days go wrong long before anyone puts a boot on. They go wrong at the kitchen table, when we draw a line between two points on a 1:50,000 map, decide it looks about six miles, and forget that the map is a picture of ground we have never stood on. A moorland is not a flat green field with a path painted on it. It is a wet, tilted, weather-making machine, and the map tells you exactly where its teeth are — if you know how to look.

Before you plan a route, spend ten minutes reading the shape of the land rather than the distance. Ask three questions: how steep is it, how wet is it, and where does the wind and rain come from? The answers are all on the paper in front of you.

Where the Contours Crowd, the Ground Will Bite

Contour lines are the most honest thing on a map. On a 1:25,000 sheet each line is ten metres of height, and the spacing tells you the angle of the slope. Lines a centimetre apart mean a gradient you will feel in your calves within fifty paces. Lines two or three centimetres apart mean a gentle ramp you can chat on.

Two things are worth marking in pencil before you set off:

• Crowded contours on the direct line. A straight-line route that cuts across tight contours is a climb you did not plan for. Naismith's rule gives you roughly an hour per five kilometres plus half an hour per 300 metres of ascent — but that arithmetic assumes you can walk in a straight line, and on a steep heather slope you cannot.
• The crag symbols. Black hachures, or the jagged edge where contours break, mean rock. Even a small band of crag can turn a descent into a scramble, and wet gritstone or gabbro is genuinely slippery.

On a 1:50,000 map you lose the fine detail, so treat any cluster of contours with suspicion and check it on the larger scale before you commit.

Gullies: Handy in Summer, Serious in Winter

Look for contour lines that form a narrow V pointing uphill, usually with a blue line running down the middle. That is a gully, and it is the steepest, most sheltered line on the hillside. In summer, a gully can be a lovely shaded way up a hot slope, and the stream water is usually clean enough to drink if you are high and above any grazing.

In winter and early spring, the same gully is where snow accumulates, drifts, and forms cornices on the lip. It is also where a slip becomes a fall rather than a slide. If the gully faces north or east and it is between November and April, assume there is old snow lying in it, plan around it, and never use one as an escape route in poor visibility.

Bog Is a Reading Skill, Not a Surprise

Nobody enjoys discovering a bog by stepping into it. Fortunately, bogs announce themselves on the map and in the vegetation.

On the map, look for flat or gently undulating ground with sparse, wandering contours, and for the blue marsh symbols and small blue dashes that mark wet ground. Watch the names, too: mire, moss, carse, flow, hags and sike are all strong hints. In the Pennines and the Southern Uplands, a route that crosses a plateau rather than following a ridge edge will almost always be wetter than you expect.

On the ground, the warnings are clear once you know them: white cotton-grass tufts bobbing in the breeze, dark sphagnum with a faint rusty tinge, purple moor-grass tussocks, and rushes standing in patches. Peat hags — broken, eroded blocks of peat — mean you will be stepping up and down constantly. A route across a bog can easily take half as long again as the map suggests, so build that into your timing rather than discovering it at four in the afternoon.

What the Sky Says Before the Forecast Updates

Mountain forecasts are good, but they are broad. The sky is local and immediate.

• Lenticular clouds — smooth, lens-shaped stacks sitting over a summit — mean strong winds at height. Expect gusts on the tops that are much stronger than anything in the valley.
• Cumulus building early and fast means convection. If the tops start to grow flat and dark, or you hear thunder, get off high ground and away from gullies and streams.
• A sudden drop in wind, still air, and a hen-roost quiet often comes before a sharp shower. On a moor, a shower can drop visibility from twenty miles to twenty metres in minutes.
• A warm front brings a milky haze, drizzle, and rising cloud base that slowly swallows the summits. If the tops are disappearing into grey and the drizzle has begun, that is your cue to navigate deliberately rather than to carry on and hope.

The Ten-Minute Check at the Car Park

Before you walk away from the car, do a short ritual. Set the map, check your compass bearing, and identify two features you can see. Note the time you expect to be back. Look at the sky and decide what would make you turn around — a cloud base below your highest point, wind you cannot stand upright in, or a route that has turned into a stream.

Wild camping on the moors is a real pleasure: a pitch on dry, level ground well away from water and paths, a stove rather than a fire, everything carried out. In Scotland, camping on unenclosed land is generally permitted under the Land Reform (Scotland) Act 2003. In England and Wales you need the landowner's permission, so check before you plan a night out.

Reading the landscape is not a substitute for experience. It is what makes experience possible. The hill will still surprise you — it always does — but you will be surprised in a place you chose, at a time you chose, rather than in a place you blundered into.
